Dorman 615-977 Spindle Nut for OE Fit
Dorman 615-977 is a steel spindle nut engineered to match the fit and function of the original part on specified vehicles. Built for reliable performance, it supports proper hub and axle retention on front and rear applications across a wide range of Buick, Chevrolet, Cadillac, GMC, and Saab models.
Key Features
- Steel construction for durable service in driveline and axle applications
- 36 mm hex size with M24-1.5 thread size
- Medium thread type for OE-style fitment
- 6-point design for secure tool engagement
- Non-slotted spindle nut design

Detailed Description
This Dorman spindle nut is built to replace the original hardware used on select GM and Saab platforms. The part number 615-977 is specified for vehicles such as the Chevrolet Malibu, Chevrolet Equinox, Buick Encore GX, Cadillac CT4, and GMC Terrain, along with additional front and rear applications listed in the fitment data. Its steel material and M24-1.5 thread profile help maintain the correct clamping and retention characteristics required at the spindle assembly.
This part cross-references OE numbers 11611687 and 13217120 for the same application. If you are servicing a Chevrolet Malibu front hub, a Buick LaCrosse front spindle, or a Cadillac CTS rear assembly, Dorman 615-977 provides the correct thread diameter, hex size, and OE-style configuration for the job.
What It Helps Address
- Loose or worn spindle nut hardware during hub service
- Incorrect thread size or hex size on replacement repairs
- Loss of proper axle or hub retention at the spindle
- Fitment issues when replacing OE hardware on GM and Saab platforms
- Service delays caused by damaged or non-matching spindle nuts
Installation Notes and Tips
Verify thread size, hex size, and position before installation. This spindle nut uses an M24-1.5 thread and a 36 mm hex, so confirm the tool setup matches the vehicle service procedure. Because the part is listed as one-time use, replace it during the repair rather than reusing the old nut. Always follow the vehicle manufacturer’s torque and assembly specifications for the final installation.
Quality Assurance
Dorman designs this spindle nut to match original part fit and function on specified vehicles. The steel construction and OE-style dimensions support consistent service on applications such as the Chevrolet Equinox, Buick Regal, and Cadillac XTS. Part number 615-977 is built for dependable replacement use in driveline and axle maintenance.
